5.1 Functional description
Similarly to computed tomography or magnetic
resonance imaging, sectional images can be
generated with CBCT. With CBCT, an X-ray tube
and an imaging sensor opposite it rotate around
a seated or standing patient. The X-ray tube
rotates through 180°-540° and emits a conical X-
ray beam. The X-ray radiation passes through the
region under investigation and is measured for
image generation via a detector as an attenuated
X-ray image based on grey values. Here, a large
series of two-dimensional individual images is
acquired during the revolution of the X-ray tube.
Using a mathematical calculation on the rotating
image series via a reconstruction computer, a
grey value coordinate image is generated in the
three spatial dimensions. This three-dimensional
coordinate model corresponds to a volume
graphic that is made up of individual voxels.
Based on this volume, it is then possible to gen-
erate sectional images (tomograms) in all spatial
dimensions as well as 3D views.
